First, this is heavily subjective. I don't know what your sources are but coming out with such conclusion without any research backing you up does not make this reliable at all. Second, euro is one of the strongest currency in the world, even if it falls for a bit it will not be that bad. Third, Europe has been one of the center of tourism in the world not only for its currency but for its history, tourist spots and rich culture.
I was expecting an analysis of the current global economy, not an opinionated claim without any research to back it up.
